HORSESHOE.

SPECIFICATION forming part of Letters Patent No. 369,827, datedfieptemoer 13, 1887.

Application filed April 7, 1885.

To aZZ whom it may concern.-

- Be it known that I, Joan E. WHITE, a citizen of the United States,residing at Buffalo, in the State of New York, have invented a new anduseful Improvement in Horeshoes, of which the following is aspecification.

This invention relates to improvements in sharp-calked horseshoes.

The general object of this invention isto so construct a horseshoehaving sharp calks integral with the body of the shoe that the calksshall be adapted by their construction to remain sharp until Wholly wornoff, thus adapting such shoes for use on street-car horses and horsesotherwise so employed that very expensive shoes and shoes requiringfrequent attention are unsuited to them.

A sheet of drawings accompanies this specification as part thereof.

Figure 1 of these drawings is a bottom or face View of a horseshoeembodying this invention. Fig. 2 represents alongitudinalsection thereofon the line 2 2, Fig. 1. Fig. 3 is a front end View thereof; and Figs. 4and 5 represent detail crosssections on the lines 4 4 and 5 5, Fig. 1.

Like letters of reference indicate corresponding parts in the severalfigures.

This improved horseshoe is constructed with a toe-clip, 0, top bevel, b,an under bevel, b", nail-creases c c, and nail'holes h h,which form nopart of the present invention. It is furthermore constructed with sharptoe and heel calks T H H integral With the body of the shoe,perpendicular to its sole, and of uniform thickness from top to bottom,so as to remain sharp and uniformly effective until they are They willnot Wear off on street-railways in less than from four to eight days,with an average life of, say, six days, which is ample to render theiruse economical. The smooth shoes may then be removed and preserved forsummer use. Said toe-calk T is supported by a thick toe end and iscomposed Serial No. 161,457. (No model.)

of a main portion, m, at right angles to the hauling strain, and bracesor stays s perpendicular thereto in fr0nt,whereby the thin main portionor calk proper is adapted to sustain said strain,while they wear awaytherewith, so as not to impair the aforesaid mode of operation.v More orless of such stays will be employed on shoes for different grades ofwork.

The heel-calks H H are preferably longi tudinal and in line with therespective nailcreases, as shown in Fig. 1, and are supported externallyby ogee edges 0 projecting beyond them, as best seen in Figs. 4 and 5.

One-eighth of an inch is considered a maximum thickness for the calks. Aless thickness will afford sufficient strength in die-swaged shoes formedium work. The shoes are designed to be so made; but my presentinvention is not intended to be limited to any par ticular mode ofmanufacture.

Having thus described my said improvement in horseshoes, I claim as myinvention and desire to patent under this specification-- 1. An improvedsharp calked horseshoe having thin calks integral with the body of theshoe, perpendicular to its sole, and of uniform thickness from top tobottom, the toe'calk being at right angles to the direction. of haulingstrain. and braced in front by stays integral therewith and adapted towear away with the cal ks, substantially as herein specified.

2. An improved sharp -calked horseshoe having thin calks integral withthe body of the shoe, perpendicular to its sole, and ofuniform thicknessfrom top to bottom, the heel-calks being longitudinal and supportedexternally by ogee edges projecting beyond them, substantially as hereinspecified.

Dated at New York this 2d day of April, 1885.
